!mes, then begin the test.
To exit the test mode, momentarily push the Menu key, cycle power to the furnace, or make a valid thermostat
call for capacity or fan.
Sequence of Run Test Mode
-Turns the inducer on in 1
st
stage for 30 seconds
– Turns on the inducer on 2
nd
stage for 30 seconds
– Turns the igniter on for 10 seconds
– Turns the circula!ng blower on 1 stage compressor speed for 10 seconds
– Turns the circula!ng blower on 2 stage compressor speed for 10 seconds
– Turns the circula!ng blower on 1
st
stage gas heat speed for 10 seconds
– Turns on the circula!ng blower on 2
nd
stage gas heat speed for 10 seconds
The above sequence will repeat two more !mes unless the Run Test Mode is exited, see above.
Important: The Run Test Mode does not test fire the furnace or bring the outdoor unit on. It is designed to allow
the technician to observe each mode to ensure the IFC, inducer, igniter and circula!ng blower are performing as
intended.

1dL
IdL = Idle, no demand for cooling, heating, or fan
Ht1 = Demand for 1 stage gas heat
Ht2 = Demand for 2 gas heat
CL1 = Demand for 1 stage cooling
CL2 = Demand for 2 stage cooling
HP1 = Demand for 1 stage heat pump
HP2 = Demand for 2 stage heat pump
COf = Demand for continuous fan
dFt = Demand for outdoor unit defrost, furnace running
in gas heat mode
ARF 080 = Calculated airflow is 800 cfm
Note:
1. The status will alternate between the system mode and
the airflow request every 2 seconds.
3. If an error occurs, an E*.* will alternately flash with the
system mode and airflow request. See first example.
3. Multiply the value shown by 10 for actual airflow.
